65mm Catchment Dropper

A Catchment System is used to collect the nutrient solution from the NFT gullies and divert it into the main return pipe leading back to the NFT mixing tank.

The Catchment system usually holds 8 x NFT gullies and consists of a length of 100x50mm or 150x75mm gully with rectangular slots cut into it to insert the gullies into. The two ends of the Catchment System is sealed with gully End Caps. On the base of the Catchment System a hole is drilled through which the nutrient solution falls through into the return pipe upstand. A 65mm Catchment Dropper is glued over this hole so that the nutrient flow can fall directly into the return pipe upstand.
